Install it

Copy the prompt for your app and paste it into your agent. It walks you through the rest.

Claude, by hand

In a terminal, install the agentthemes plugin once:

claude plugin install agentthemes --marketplace https://bestagentthemes.com/marketplace.json

Then, in a Claude Code session in the Claude desktop app, type these two:

/reload-plugins
/agentthemes vector-range

It shows behind the chat after your next message. /agentthemes off clears it.

T3 Code, by hand

Download vector-range.json, then run this where you saved it:

t3 theme set vector-range.json

The scene shows as a still picture, and it needs a T3 Code build with custom theme CSS. t3 theme set t3-chat goes back.
